Improvement in hydrants

n.1. PuUNE-R, or BELL-Enorme,'PENNSYLVAN1A- To all whom it may concernBe it known that I, -D. I. Pnnlynaof Bellefontc, in the county ofCentre, and State of Pennsylvania, have invented a new and valuableImprovement in Hydrants; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation of.the same, reference being had to the annexed drawings, making a part ofthis specification, and to the' letters and figures of' reference markedthereon.

Figure l, of the drawings, is a representation of my.

invention, with the front portions of the casings removed.'

Figure 2 isa vertical cross-section of the same.

' My invention relates to hydrants, and consists, mainly, iu theconstruction and novel arrangement of devices, Awhereby 'a hydrant isrendered non-freezing, and the parts below ground arranged in a'case, sothat they can be drawn up for repairs, without excavation.

' Theletter A of the drawings designates the outer ,casefor pit-lining,of wood.

This is a rectangular' box, open at the top, which is let down into theearth, until the edgesof its top are ush with the surface. It is partlyopen at the bot'- tom, for drainage.

The supply-pipe a, from the ground, passes up i through the shelf b,arranged across the bottom of the case A, 'and is secured into anopeningin the cap c.

The cap chas a circular lip around the mouth of the opening, and aslanting shoulder, a.

When the hydrant. is pushed down into its place, the plate B, attachedto the lower end of the pipe c', meets the upper slanting face of thecap` c, and receives into a circular depression, in its own lowerslanting surface, the lip of the cap c, thus forming a secure joint.

A disk, ot' leather, may be used around the lip of the cap c, aspacking, if desired.

Attached tothe bottom of' the hydrantcase D is the lower plate Z ofthecut-oiT-a plane, circular disk,

withthree openings, c,- e', and c, one'of which, e, communicates withthe pipe c'. e' and c", are for drainage.

z is a metal plate, having a circular opening,.some what smaller indiameter-'than the upper disk t ofthe cut-oli', so that it presses uponthe upper surface of' its rim, when clamped -by the screws s s, or otherdevices, hereafter described.

The meeting-surfaces of the disks l and tare ground and'polishedperfectly smooth, so that when they are pressed together, no water canooze between them.

The upper plate tis kept in ppsition by twosmall projections attached tothe lower' surface of the clalnping-plate z, and by the curved frontwall of the shoulder or elbow r.

The water, entering-by the opening in the disk t, is conveyed throughthe elbow r, passes up through the pipe p, and out at the spout q.

The other two openings,

side vents e e.

lKeyed to the lower end of .the pipe p are the jaws a, which embrace thesides of the elbow 1.

The pipe p and jaws a thus act as a wrench, by which .the disk tisturned, to let the water on, or out it ofi'.

A small spring, m, coiled around the pipe p, n ear the top of thehydrant, is used to keep Athe jaws n down, and the disksl and t aresomewhat closed by it.

The pressure of the spring m is regulated by the nut o', working againstthe plate a'.

K K are struts, the feet of which rest on the plate z, and, beingpressed down by the spring Sfwedges c c, or both, operate principally inkeeping the disks l and tclosely together. v.

M represents a metal plate, secured firmly to the hydrantcase,"byvattaching vcleats above and belowl it.

This plateis 'so situated, that when the hydrant is -let down into theouter case A, far enough to bring the plate B in position on the cap c,it will be flush with and cover the top of the case A, and maybe securedthereto with screws in such a manner as' to .cause a pressure on thejoint at B, and thereby render itwater-tight.

When the hydrant is turned on, all the water in the pipe p and elbow/rescapes through one of the Therefore, there. can be no'freezing abovethe cut-oli'.

By the use of a coiled spring, attached under the shoulder of thespout-head N, and secured to the top plate of the hydrant, the water maybe out ofi' auto# matically.

What I claim as my invention, and desire to secure by Letters Patent, is

/1. 'The combination and arrangement of a pit-lining, A, and a removablehydrant, constructed with metal shoulder M, and attached to thesupply-pipe by the slanting j oint-plates B and e, as specified.

2. In combination with a pit-lining, A, the remov-.

able hydrant, herein described, having slanting joint B, pipes p and c',cut-oii` disks l and t, shoulder 1', jaws a, springs S and an., strutsvK, and plates M and z, constructed and arranged to operate asspecified.

3. In combination with a pit-lining, A, the removable hydrant, hereindescribed, having slanting joint Bypipes p and c', cut-oii disksl and t,shoulder r, jaws n, wedges c c, adjustable spring mf, struts K, andplates'M and c, as specified.

. 4. In combination with the cut-off plate t, with y elbow r, the platel having three apertures, viz, an inlet, e,"and outlets e and e",constructed and arranged to operate as specified.

In testimony that I claim the above, I have hereunto subscribed my name,in the presence of two witnesses.
